Application filed April 28, 1922. Serial No. 557,163.

and State of Ohio, have invented a new and useful Valve-Spring Compressor, of which thei ollowing is a specification.

The device forming the subject matter of this application is adapted to be employed for compressing the valve springs in internalcombustion engines, to the end that the retaining pintor the spring may be withdrawmand the invention aims to provide a simple device which can be used in variousways, depending on how the valve is mounted in the engine.

It within the province oi" the disclosure to improve generally and to enhance the utility of devices ofthat type to which the invention appertains.

l Vith the above and other objects in view,

.which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, with in the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit oi the invention. I

In the accompanying drawings:

Figure 1 shows in side elevation, a device constructed in a'cc'ordancewith the invention, mounted in place on an internal combustion engine; Figure 2 is an elevation wherein the structure is viewed at right angles to the showing 01 Figure 1.; Figure 3 is a side elevation wherein the device is re-assembled for use in connection with a valve of a type differing from that shown in Figure 1; Figure 1- is a cross section on the line 1- 1 of Figure 1. a

Referring to Figures 1, 2 and 4, the device comprises amain member 1 supplied at its lower end with a transverse foot 2 having a roughened upper surface 3, there being a slot 52 in the foot 2. The foot 2 is provided with an opening 4 disposed to the rear of the slot 52. A stop 5 is pivoted at 6 to the main member 1, and issupplied at its outer end with upstanding fingers 7. In the upper end of the main member 1 there is a slot 8. The main member 1 has a longitudinal rack disposed on opposite sides of the slot 8.

The numeral 9 marl s a compression lever located in the slot 8 of the main member 1 and carrying, at one end, a pivot element 11. The lever 9 1s provlded with an opening 12 disposed adjacent to'the pivot element 11. A depending head 14 is provided, and is mounted on the pivot element 11, the head 14 having a recess 15 in its end, and being provided with a transverse passage 16.

Openings 17 are formed in the lever 9 intermediate the ends thereof, and in any of the openings 17 may be mounted a pivot element 18, adaptedto be mounted in any one of a plurality of openings 19 disposed in the main member 1 and spaced apart longitudinally oi the main member.

A loop-shaped latch 20 surrounds the main member 1 and cooperates with the rack 10, the latch 20 being detachably pivoted in the opening 12 of the lever 9. A combined brace and guide 21projects from the head 14. and passes through the slot 8 in the main member 1, nuts 22 being threaded on thepart 21, and being located on opposite sides of the main member 1.

In Figure 1 of the drawings, there is shown a portion 23 of an engine frame, wherewith a valve 24 cooperates, the valve being carried by a stem 25 slidable in the frame 23. The stem 25 carries an abutment 26. A valve spring 27 engages the abutment 26 and the engine frame 23. A retainer 28, such as a pin, is mounted in the valve stem 25, and holds the abutment 26 infplace to receive the thrust of the spring 27.

hen it is desired to remove the spring 27, the head 14 is seated on the engine frame 23, over the valve 24, the stop 5 engaging the spring 27 and serving so to position the valve stem 25 that the same is alined with theslot 52in the foot 2, the foot being engaged beneath the abutment 26 on the valve stem 25. WVhen the lever 9 is swung upwardly into the position shown in Figure 1 the abutment 26 is raised, the spring 27 is compressed, and the retaining pin 28 is disposed belowthe foot 2, the pin 25 moving downwardly through the slot 52 in the foot. When the parts are arranged-as above set forth, the pin or retainer 28, obviously, may be withdrawn. The latch 20, cooperating with the rack 10 holds the parts in the positions shown in Figure 1, the memher 1 being guided between the nuts 22 on the part 21.

Suppose, however, that the device is to be into an out-ot-the-way position.

iii)

used in connection with a valve and a cage, the valve-cage being removable from the engine frame. When the )arts are arranged as shown in Figure 3 the valve stem is denoted by the numeral 30, the valve appearing at 29, the cage at 31, the spring at 32, the abutment at 33 and the retaining pin at 3 1. The foot 2 of the member 1 is placed on a bench or other support 35 and is connected thereto by a securing element 36 extended through the opening at in the foot 2. The stop 5 is swung baclrwardly The head 1% is mounted on the pivot element 18 and the lever 9 is connected to the member 1 by the pivot element 11, the parts 1 and 1 1 being interchanged from he positions shown in Figure 1. The latch 20 is mounted in one of the openings 1?. The valve 29 rests on the roughened surface 3 of the foot 2, and the part 14 engages the spring abutment 33. When the lever 9 is swung downwardly, the foot 1 1 compresses the spring 32, whereupon the retaining pin 24 may be withdrawn from the valve stem 30, through the passage 16 in the head 1 1.

lVhat is claimed is:

1. A device of the class described comprising a main member provided at one end with a transverse foot and having a longitudinal rack; a head cooperating with the foot to compress a valve-spring; a brace carried by the head and receiving the main member slidably; a lever; pivot elements connecting the lever with the main member and with the head; and a latch mounted pivotally on the lever and coacting with the rack to hold a valve-spring compressed.

'2. A valve-spring compressor, a main member provided at one end with a transverse foot; a spring-engaging stop mounted pivotally on the main member adjacent to the foot; :1 head cooperating with the foot to compress a valve-spring; a lever; and pivot elements connecting the lever with the main member and with the head.

3. In a valve-spring compressor, a main member provided at one end with a transverse i'oot; a spring-engaging stop pivotally mounted on the main member and disposed adjacent to the foot; a head cooperating with the foot to compress a valve-spring;

esa-ave a brace carried by the head and receiving the main member slidably; a lever; and pivot elements connecting the lever with the main member and the head.

4. In a valve-spring compressor, a main member provided at one end with a transverse t'oot; a spring-engaging stop pivotully mounted on the main member and disposed adjacent to the foot; a head cooperating with the foot to compress a valvespring; a lever; pivot elements connecting the lever with the main member and with the head; and a latch mounted pivotally on the lever, the main member having a rack wherewith the latch coacts to hold a valvespring compressed.

5. In a valve-spring compressor, a main member provided at one end with a transverse foot, and having a longitudinal rack; a springengaging stop pivotally mounted on the main member and disposed adjacent to the foot; a head cooperating with the foot to compress a valve-spring; a brace carried by the head and receiving the main member slidably; a lever; a latch mounted pivotally on the lever and coacting with the rack to hold a valve-spring compressed, and pivot elements connecting the lever with the main member and with the head.

6. In a valve-spring compressor, cooperating elements cooperating to compress a valve-spring and comprising a main member provided at one end with a transverse toot having an opening, and a head coacting with the foot and the opening and having a transverse passage; a lever; and means for mounting either of said cooperating elements pivotally on the lever intermediate the ends thereof, and for mounting the other of said cooperating elements on the lever at one end thereof, to aliord an interchange in the positions of said cooperating elements on the lever.

In testimony that-'1 claim the foregoing my own, I have hereto affixed signature in the presence of two witnesses.
